The important caution items in ship navigation are to ensure the safety of crews and carried goods, in order to improve the safety of the navigation, fire protection and life saving, structural fire separation, escape channels and the like of the ship are required to be taken as the key points of ship design in the ship construction process, wherein the structural fire separation is to divide the whole ship into different areas according to the room size, the functions and the like, and a fire-proof structure is designed among the areas so as to limit the spread of fire to the maximum extent after a certain area catches fire and provide precious time for the crews to escape.
Fire protection structures between areas are currently designed according to the international maritime life safety act (SOLAS), where it is specifically required that "the space enclosed behind the ceiling, panelling or lining should be separated by closely-mounted wind-shielding strips with a spacing of not more than 14 m". However, in practice, it is often the case that the distance is more than 14m, and therefore, it is necessary to design a weather strip (smoke barrier structure) for preventing smoke from passing through, and corresponding cabin penetrating members are provided to ensure smoke blocking effect when the pipeline and the cable pass through the weather strip.
The existing smoke baffle plate structure is mainly made of steel plates and integrally fixed on a ship body, fireproof cotton is laid on one side of each steel plate, through holes for pipelines and cables to pass through are further formed in the steel plates, and the pipelines and the through holes, the cables and the through holes are all plugged through the fireproof cotton. Although the smoke baffle plate structure plays a role in fire prevention and separation, the steel plate is thick and heavy, so that the load capacity of the ship is reduced to a certain extent, and the transportation efficiency of the ship is influenced. In addition, although the fireproof cotton is filled between the cables and the through holes, gaps still exist among the cables in the bundled mode, and when a fire disaster happens, smoke still flows out of the gaps of the cables, so that the fireproof separation effect of the smoke baffle structure is poor. In addition, the steel plate is thick, so that the arrangement of the through holes is not facilitated to a certain extent, and the cable and the pipeline are not facilitated to penetrate.

s3: fixing the baffle plate structure on the combined frame;
s4: laying a fireproof material on one side of the baffle structure and the position corresponding to the gap, and fixing the fireproof material through a fixing piece;
s5: and injecting flame-retardant filler into the cabin penetrating component.
Furthermore, the cabin penetrating piece is provided with an injection hole and an air hole.
Further, the baffle structure is galvanized steel sheet.
Furthermore, the thickness of the galvanized steel plate is 1 mm-3 mm.
Further, the fixing member includes a stud and a cap, and the step S4 includes welding the stud to the baffle structure.
Furthermore, the combined frame is formed by welding channel steel, and the cross section of the channel steel is C-shaped.
Furthermore, the channel steel comprises a plurality of vertical channel steel arranged at intervals and transverse channel steel which connects the vertical channel steel in series, one end of each vertical channel steel is fixedly connected with the deck, and the other end of each vertical channel steel is fixedly connected with the transverse channel steel.
Further, drawing each cable in the penetration piece to a required length is also included in step S5.
Furthermore, the baffle structure is provided with a pipeline in a penetrating mode, and the corresponding gap position comprises a gap between the pipeline and the corresponding through hole in the baffle structure, and a gap between the bottom of the baffle structure and the ceiling.
Further, the ceiling is vertically spaced from the bottom of the baffle structure, and the step S4 includes bending the fire-retardant material from the side of the baffle structure to the side of the ceiling.
Compared with the prior art, the installation method of the smoke baffle structure of the ship has the following beneficial effects that: by adopting the smoke baffle structure installed by the installation method, under the condition of meeting the structural strength, the total weight of the combined frame and the smoke baffle structure is less than that of a steel plate in the prior art, so that the total weight of the ship is reduced, a deck can load more cargoes, and the carrying capacity of the ship is improved. In addition, because the fire-retardant filler is injected into the cabin penetrating piece, the fire-retardant filler can seal gaps among cables, thereby avoiding the situation that smoke leaks from the cable gaps, improving the fire-proof separation performance of the smoke baffle structure and further improving the safety performance of ships. In addition, the baffle plate structure is thin, so that the baffle plate structure is very easy to cut and process, the arrangement of through holes is facilitated, and the laying of the baffle plate structure in various narrow areas is facilitated.
